Abstract

Cellulosic fabrics are creaseproofed by treating them with an aqueous medium until they contain 10-100% by weight of water and then treating them with a solution of formaldehyde in a dehydrating medium, i.e. a medium which is itself a dehydrating agent or is an aqueous solution of a dehydrating agent containing at most 50% by weight of water. The dehydrating medium may be glacial acetic acid or a calcium chloride solution of from 50% by weight concentration up to saturation. The fabric may first be padded to 10-100% by weight pick up with an aqueous solution of a strong acid or a salt of a weak base with a strong acid, e.g. phosphoric, hydrochloric, hydrobromic, sulphuric, trichloroacetic, formic or toluene sulphonic acid, ammonium chloride or ammonium sulphate, which preferably has an acid strength varying between 0.01 and 20% by weight and may then substantially immediately be treated with the formaldehyde solution in the dehydrating medium which may contain 0.01-2% by weight of acid. Alternatively the fabric may first be padded to a 10-100% by weight pick up with water or an aqueous solution containing 0.1-1% by weight of an anionic, cationic or narionic wetting agent numerous examples of which are given and then impregnated substantially immediately with the formaldehyde solution in the dehydrating medium which may contain 0.01-20% by weight of a strong acid. Before or after the formaldehyde treatment the fabric may be treated with 2-18% by weight of a crease-proofing resin, e.g. dimethylol urea, dimethyl ether of urea-formaldehyde resin, trimethylol melamine, methylated trimethylol melamine, tetrahydro-5-hydroxy-2(1H)-pyrimidone-formaldehyde, cyclic ethylene urea-formaldehyde, urea formaldehyde, dimethylol ethyl triazone, butediene diepoxide, bisphenol-A epichlorhydrin, 1,4 bis (2,3 epoxy-propoxy) benzene, 1,3-bis (2,3-epoxy propoxy) octane and ethylene glycol diglycidyl ether resins, which may be cured by heating to 178 DEG C. for 1 1/2 minutes. Fabrics comprising cotton, linen, hemp, jute, ramie, sisal, viscose rayon, cuprammonium rayon, cellulose acetate, cellulose acetate-propionate, cellulose acetate-butyrate or ethyl cellulose fibres alone or in admixture with nylon, polyacrylonitrile or polyester fibres may be treated.
